WATCH-BOW FASTENER.

SPECIFICATION forming part of Letters Patent No. 496,830, dated May 2, 1893. Application filed January 14, 1893. Serial No. 458,345. (No model.)

To all whom it may concern:

Be it known that I, RUDOLPH M. HUNTER, of the city and county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Watch-Bow Fasteners, of which the following is a specification.

My invention has reference to watch bow fasteners, and consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings which form a part thereof.

This application, Case No. 237, has particular reference to the means employed for fastening the watch bow to the pendant, and also to the means for holding the push pin in an outward or inward position such as re quired in winding or setting the watch.

In carrying out my invention I provide the pendant with slotted openings upon its sides, a portion of which openings is of larger diameter than the remaining part. The watch bow has its ends provided with annular collars or fianges which are adapted to pass through the large parts of the slotted openings and be moved so that the narrow part of the opening receives the neck or small diameter of the watch bow end. The watch bow is supported in this position by means of an external sleeve fitted to the outside of the pendant and in which it is journaled. This outside sleeve is secured to the pendant in any suit-able manner. An internal sleeve is adapted to fit within the pendant and preferably be the means for holding the external sleeve in position upon the pendant, and at the same time form a shoulder over which a spring carried by the push pin snaps to hold the said push pin in an outward or inward position as required in setting or winding the watch.

My invention will be better understood by reference to the accompanying drawings, in which Figure 1 is a sectional elevation of awatch pendant and its connections embodying my invention. Fig. 2 is a side elevation of the pendant removed; and Figs. 3, 4 and 5 are sectional elevations of structures illustrating difierent forms of my invention.

A is the pendant and is provided upon the outside with a sleeve B having its sides pressed outward to form ears having apertures b as bearings in which the ends of the watch bow C are journaled. The free ends of the watch bow are provided with annular grooves c or are so shaped as to form collars or flanges upon the ends. The opposite sides of the pendant A are provided with slotted openings having the large portions D and the narrow portions cl, the former being of sufficient size to receive the end of the bow, and the latter being adapted to fit the neck 0 or smaller diameter so as to prevent the collar on the end of the bow from being pulled outward.

In Figs. 1, 2, 3 and 4: the slotted openings in the pendant are shown with the large part D at the bottom and the small part cl at the top, so that after the ends of the watch bow are inserted, the sleeve B is pushed upward to lock the ends of the bow in the small parts of the slotted openings of the pendant. The sleeves B are then secured in any suitable manner,several ways beingshown. The watch bow will then be free to swing on the bearings b as journals, and also against the upper parts d, of the openings and the collars on the end of the bow will prevent it being pulled outward. The shoulder upon the inner side of the annular groove 0 will also prevent the bow being thrust inward, and this is further provided for by arranging upon the inside of the pendant an annular ring shaped part E against which the ends of the bow would strike if thrust inward.

In Fig. 1 the part E is provided with screw threads which simultaneously screw into the internal surface of the pendant A and the sleeve B so that the sleeve B is locked to the pendant. The ends of the watch bow pre vent the sleeve B from revolving upon the pendant and consequently the parts A and B maintain a fixed relation once the internal piece E is screwed into place.

F is the push pin and is provided at the top with the usual crown H. Clamped between the push pin and the crown is a spring sleeve G which is provided with a projection g adapted to snap over the shoulder e of the internal sleeve or cylindrical piece E. The push pin may be pulled outward or pushed inward as required for setting or winding the watch, and the spring G in connection with the shoulder will hold the push pin in position and yet will permit it to be freely rotated. The lower end of the spring G is flanged outward so as to catch upon the bottom of the shoulder and thus prevent the push pin being completely pulled out. To adjust the position of the shoulder withinthe pendan'aone or more washers T maybe employed between j the top of the pendant and the shoulder of the cylindrical piece E, or a single spring washer may be employed.

In the construction shown in Fig. 3 the internal sleeve or cylindrical piece E is shown as havin g no direct connection with'thesleeve B which is screwed upon the inside of the.

pendant A alone. sition on the pendant by a small screw J.

The sleeve is held in .po-.

sleeve 13 has a flange I at itsbottom. The? sleeve is .pushed up from the bottom of the? pendant so that the inward flange I comes; against the "shoulderon the pendant. The

internalsleeve E is then screwed upon the inside of the external'sleeve B and presses upon the upper part'of t'hependant thus acting'asa 'nut to hold the sleeve to the pendant.

In the construction shown in Fig. 5 the pendant A is provided with a projecting shoulder K near its'lower'part. The sleeve B is fitted down upon the shoulder K and the internal sleeve or cylinderE is screwed upon the interiorof the pendant Aa'nd .provided with a flange which fits over the upper part of'the sleeve Band clamps itinposition upon the pendant. In this construction the slotted openings 61, D,'are inverted sothat the larger part D comes at the top. After the watch bow ends are inserted the sleeve B is pushed downward and locks'the ends of'the bow to the pendant, and the locking internal piece or cylinder E-isscrewed into place.

It will thus be seen that'in Figs. 1, 4 and 5 the sleeve E performs the dual duty of lockingthe-external sleeve B in position upon the pendant, and also forms a shoulder with which the spring G works for holding the push pin in either position.

It'is quite evident that the slotted openings d D maybe of any irregular shape in place of the shape shown in solid lines in Fig. 2; for instance, the irregular-shape indicated in dotted lines in Fig. 2 may be employed so that after the bow ends are inserted theymay be turned horizontally and then longitudinally in the pendant to lock them in position. It is also evident that while I prefer toimake the external sleeve B in one piece, it might be made in two pieces joined longitudinally on the pendant, and the said parts secured by screws similarly to the manner shown in Fig. 3. These details are immaterial to the general structure of the invention.

I do not confine myself to the mere details; of construction as they may be modified without departing from the principles of my in-:
